OBVERSE

The obverse of this coin features the fourth effigy of Queen Elizabeth II, a portrait imbued with dignity, continuity, and royal presence. Calm. Formal. Timeless. The design recalls an era of British numismatics immediately recognized by collectors, where each line of the portrait carried the authority of the Crown and the memory of an unparalleled reign. Polished to a luminous Proof finish, the platinum surface gives the effigy a sharp, ceremonial gleam. This edition marks a world first: the iconic effigy appears on an official Royal Mint platinum coin, elevating a historic portrait into a new form of precious metal. 

REVERSE

The reverse bears the issuing authority of the United Kingdom, as well as inscriptions related to the coin's legal tender status: "2026" - the year of issue, and "100 POUNDS" - the face value.
